Heat is needed to assist in dissolving polyvinyl alcohol because it increases the kinetic energy of the solvent molecules, allowing them to break the intermolecular forces holding the polymer chains together. This results in a faster and more thorough dissolution of the polyvinyl alcohol in the solvent.

How much alcohol is needed to sterilize water?
To effectively sterilize water using alcohol, a concentration of at least 60-70% alcohol is recommended. The exact amount depends on the volume of water being treated. Typically, a small amount of alcohol is needed to mix with the water or to swab the container.

How do you dissolve phenlthphalein powder?
Phenolphthalein powder can be dissolved in a solvent like ethanol or propylene glycol. Simply add the powder to the solvent and stir until it dissolves completely. Adjust the solvent amount as needed to fully dissolve the powder.
What is the effect of dissolving salt in water on boiling point of water?
Dissolving salt in water increases the boiling point of water. This is because the salt disrupts the hydrogen bonds between water molecules, making it more difficult for them to escape as vapor. As a result, more heat is needed to raise the temperature of the solution to its boiling point.
How do you remove polyvinyl alcohol applied as stiffener in the fabric?
To remove polyvinyl alcohol applied as a stiffener in fabric, soak the fabric in warm water for about 30 minutes to dissolve the PVA. Gently massage the fabric to help break down the PVA, then rinse it thoroughly with water. Repeat the process if needed, or wash the fabric in a washing machine with mild detergent.
What is correct assist where needed or assist were needed?
The correct phrase is "assist where needed." This expression indicates providing help or support in situations that require it. "Assist were needed" is grammatically incorrect, as "were" is the past tense of "be" and does not fit in this context.
What is bad about polyvinyl alcohol?
Polyvinyl alcohol (PVA) can pose environmental concerns due to its persistence in the environment and potential to contribute to microplastic pollution. Additionally, while it is generally considered non-toxic, excessive exposure can lead to skin or respiratory irritation in some individuals. Its production process may also involve harmful chemicals, raising concerns about occupational safety and environmental impact. Lastly, PVA's solubility in water limits its use in certain applications where durability is needed.

What alcohol do humans use you assemble molecules needed for life?
The alcohol that humans use to assemble molecules needed for life is lactic acid which is made through fermentation. This is equivalent to ethanol which is produced in plants.
How many dribbles are typically needed for an assist in the NBA?
In the NBA, an assist is usually credited when a player makes a pass that leads directly to a made basket, and typically only one or two dribbles are needed before the shot is made.
